- * The panel is initialized based on data given in the js object passed
- * as window.arguments[0]. The object must have the following fields set:
- *   @ action (String). Possible values:
- *     - "add" - for adding a new item.
- *       @ type (String). Possible values:
- *         - "bookmark"
- *           @ loadBookmarkInSidebar - optional, the default state for the
- *             "Load this bookmark in the sidebar" field.
- *         - "folder"
- *           @ URIList (Array of nsIURI objects) - optional, list of uris to
- *             be bookmarked under the new folder.
- *         - "livemark"
- *       @ uri (nsIURI object) - optional, the default uri for the new item.
- *         The property is not used for the "folder with items" type.
- *       @ title (String) - optional, the default title for the new item.
- *       @ description (String) - optional, the default description for the new
- *         item.
- *       @ defaultInsertionPoint (InsertionPoint JS object) - optional, the
- *         default insertion point for the new item.
- *       @ keyword (String) - optional, the default keyword for the new item.
- *       @ postData (String) - optional, POST data to accompany the keyword.
- *       @ charSet (String) - optional, character-set to accompany the keyword.
- *      Notes:
- *        1) If |uri| is set for a bookmark/livemark item and |title| isn't,
- *           the dialog will query the history tables for the title associated
- *           with the given uri. If the dialog is set to adding a folder with
- *           bookmark items under it (see URIList), a default static title is
- *           used ("[Folder Name]").
- *        2) The index field of the default insertion point is ignored if
- *           the folder picker is shown.
- *     - "edit" - for editing a bookmark item or a folder.
- *       @ type (String). Possible values:
- *         - "bookmark"
- *           @ node (an nsINavHistoryResultNode object) - a node representing
- *             the bookmark.
- *         - "folder" (also applies to livemarks)
- *           @ node (an nsINavHistoryResultNode object) - a node representing
- *             the folder.
- *   @ hiddenRows (Strings array) - optional, list of rows to be hidden
- *     regardless of the item edited or added by the dialog.
- *     Possible values:
- *     - "title"
- *     - "location"
- *     - "description"
- *     - "keyword"
- *     - "tags"
- *     - "loadInSidebar"
- *     - "folderPicker" - hides both the tree and the menu.
- *
- * window.arguments[0].performed is set to true if any transaction has
- * been performed by the dialog.
